The percussion tool includes a piston positioned in sliding contact within a casing. The piston includes an inner wall and an outer wall, where the inner wall defines a passageway extending longitudinally therethrough. The outer wall is positioned in close fitting relationship with an internal surface of the casing. One or more coatings are disposed on at least one of the casing's internal surface and/or the piston's outer wall. A flow tube may be placed through the passageway such that an outer wall of the flow tube is in a close fitting relationship with the piston's inner wall. One or more coatings can be disposed on at least one of the piston's inner wall and/or the flow tube's outer wall.

摘要： An earth boring drill bit having an alternate path to allow cuttings to be ejected or evacuated from the drill bit and up the bore hole is disclosed. The evacuation hole of the present disclosure allows larger sized cuttings to evacuate from the bit without having to be continually ground by rolling cone cutters until the cuttings are small enough to follow a path around the edge of the shirttail of the bit and up the borehole. A cuttings restrictor is disposed at the inlet of the evacuation hole. The cuttings restrictor ensures that only cuttings that are sized to move completely through the evacuation hole and exit the drill bit are allowed to enter the evacuation hole.

摘要： A method, system, and apparatus for non-destructively characterizing one or more regions within an ultra-hard polycrystalline structure using eddy current measurements. The apparatus includes an eddy current measuring device having at least one terminal, a leached component comprising a polycrystalline structure, a first wire, and a probe. The leached component includes a cutting surface and an opposing second surface. A portion of the polycrystalline structure extending inwardly from the cutting surface has at least a portion of a catalyst material removed from therein. The first wire electrically couples the terminal to the probe, which is placed in contact with the cutting surface. The eddy current is measured one or more times and compared to a calibration curve to determine an estimated leaching depth within the polycrystalline structure. A data scattering range is ascertained to determine a relative porosity of the polycrystalline structure or the leaching quality within the polycrystalline structure.

Primary PDC cutters on the primary cutter row are set in accordance with a single set methodology. Backup PDC cutters on the secondary cutter row are set in accordance with a methodology wherein a radial position of each backup PDC cutter in the secondary cutter row is offset from a radial position of each primary PDC cutter in the primary cutter row. The blade further includes a tertiary cutter row. Additional backup PDC cutters on the tertiary cutter row are set in accordance with a methodology wherein a radial position of each additional backup PDC cutter in the tertiary cutter row is offset from a radial position of each primary PDC cutter in the primary cutter row. The backup cutter setting methodology is effectively radially positions the included backup PDC cutters (in the secondary cutter row and/or tertiary cutter row) between primary PDC cutters in the primary cutter row.

摘要： Surface texturing is employed to modify the topography of one or more surfaces (radial or cylindrical) of the bearing system for a roller cone rock bit. The surface texturing results in a dimpled surface which retains additional lubricant helpful in reducing friction in the boundary and mixed lubrication regimes. Shot peening is disclosed as one method for texturing the desired surface.

摘要： A method and apparatus for non-destructively determining the wear resistance of an ultra-hard polycrystalline structure after being coupled to a downhole tool using capacitance measurements. The apparatus includes a capacitance measuring device having a positive and negative terminal, a leached component comprising a polycrystalline structure that has been coupled to a downhole tool, a first wire, and a second wire. The first wire electrically couples the positive terminal to a surface of the leached component and the second wire electrically couples the negative terminal to a surface of the downhole tool. The capacitance is measured for the leached component one or more times and compared to a calibration curve that shows a relationship between capacitance values and wear resistance, thereby allowing determination of an estimated wear resistance for the polycrystalline structure.
